uma revis{\~a}o sistem{\'a}tica utilizando a ferramenta
ProKnow-C para a identifica{\c{c}}{\~a}o dos principais
m{\'e}todos para a fabrica{\c{c}}{\~a}o de componentes de um
elemento sensor cer{\^a}mico capacitivo na forma de filme poroso,
assim como a an{\'a}lise bibliom{\'e}trica das fontes
selecionadas atrav{\'e}s do software VOSviewer. Foram
identificadas 18 t{\'e}cnicas de conforma{\c{c}}{\~a}o de
filmes de cer{\^a}micas porosas em 40 publica{\c{c}}{\~o}es.
Foram identificadas 6 t{\'e}cnicas de manufatura aditiva para a
fabrica{\c{c}}{\~a}o dos eletrodos em 45
publica{\c{c}}{\~o}es. Os m{\'e}todos e aplica{\c{c}}{\~o}es
encontrados foram descritos. Ap{\'o}s as an{\'a}lises destes
dados, juntamente com a experi{\^e}ncia dos membros do grupo de
pesquisas na pesquisa e desenvolvimento dos elementos sensores
monol{\'{\i}}ticos, principalmente no processamento das
cer{\^a}micas, as t{\'e}cnicas para a conforma{\c{c}}{\~a}o do
elemento sensor foram selecionadas. Tape casting e screen printing
foram as t{\'e}cnicas que se mostrou mais interessantes para a
fabrica{\c{c}}{\~a}o de filmes cer{\^a}micos porosos
autossustent{\'a}veis. Considerando que o material met{\'a}lico
dos eletrodos do elemento sensor dever{\'a} apresentar baixa taxa
de oxida{\c{c}}{\~a}o e a camada formada pelo eletrodo deve
penetrar apenas nos poros superficiais grandes, foi selecionada a
t{\'e}cnica direct ink writing para a fabrica{\c{c}}{\~a}o dos
eletrodos. ABSTRACT: This work aims to propose techniques for the
conformation of capacitive ceramic sensor elements through
systematic review and bibliometric analysis of the literature.
Humidity sensors are of significant importance for several
applications, especially for the application in environmental
monitoring. The sensor element must be reliable, have mechanical
and chemical resistance, and be replicable to be used safely in
hostile environments and with difficult access for maintenance.
The main objective of the research and development of capacitive
porous sensors at INPE is to monitor the relative humidity of the
air and soils installed in the INPE Data Collection Platforms
(PCDs). Other uses of the sensor elements are for agriculture and
monitoring of landslides. The sensor elements in the monolithic
form (cylindrical inserts) are already developed, and the sensor
system (with the electronic part included) is under development.
The sensor elements of the film type, which allow the
miniaturization of the system, are in the research step. Thus, the
manufacturing methods of these sensor elements are of significant
importance to achieve the elicited requirements. In this work, a
systematic review was carried out using the ProKnow-C tool to
identify the main methods for the manufacturing of components of a
capacitive ceramic sensor element in the form of a porous film, as
well as the bibliometric analysis of the selected sources using
the VOSviewer software. The study identified eighteen porous
ceramic film conformation techniques in 40 publications. The
research identified six additive manufacturing techniques for the
manufacture of the electrodes in 45 publications. The methods and
applications found were described. After the analysis of these
data, along with the experience of the members of the research
group in the research and development of the monolithic sensor
elements, mainly in the processing of ceramics, the techniques for
the conformation of the sensor element were selected. Tape casting
and screen printing are the techniques that proved to be most
interesting for the manufacture of self-sustaining porous ceramic
films. Considering that the metallic material of the electrodes of
the sensor element must present a low oxidation rate and the layer
formed by the electrode must penetrate only the large superficial
pores, the direct ink writing technique was selected for the
manufacture of the electrodes.",
